Having the same problem, makes a particularly good app rather annoying to use.
Yesterday i have updated chess app from app store and everytime i launch application i have to fill in login and password (even after one minute) it's very annoying. Before update it was ok (application correctly remember my login and passw). Can you fix it please?
